Checklist of tidepool fishes from Jericoacoara National Park, southwestern Atlantic, with additional ecological information

Abstract

Ichthyofauna from 29 tidepools in Jericoacoara National Park (Ceará State, Brazil) was sampled. A total of 733 fishes, comprising 16 species belonging to 12 families, was collected. The three most abundant species were the frillfin goby Bathygobius soporator, the sergeant-major Abudefduf saxatilis and the molly miller Scartella cristata. An invasive species from the Indo-Pacific, the Muzzled blenny Omobranchus punctatus, was also recorded. The known geographic distribution of the blenny Hypleurochilus fissicornis was extended approximately 2,500 km northward. These findings highlight the lack of knowledge of the rocky intertidal ecosystems along the Brazilian coast, an area that needs more sampling effort and ecological data. Keywords: rockpools, reef, intertidal zone, fish community, rocky shore.MACHADO, F.S., MACIEIRA, R.M., ZULUAGA GÓ MEZ, M.A., COSTA, A.F., MESQUITA, E.M.C., GIARRIZZO T. Inventário dos peixes de poças de mare do Parque Nacional de Jericoacoara, Atlântico sudoeste, com informações ecológicas adicionais.http://dx.doi. org/10.1590/1676-06032015011114Resumo: Um total de 733 espécimes de peixes, pertencentes a 16 espécies (12 famílias), foi capturado em 29 poças de maré no Parque Nacional de Jericoacoara (Ceará , Brasil). As espécies mais numericamente abundantes foram o amboré Bathygobius soporator, o sargentinho Abudefduf saxatilis e o macaco-verde Scartella cristata. Uma espécie invasora originá ria do Indo-Pacífico, Omobranchus punctatus, foi registrada para a á rea. A ocorrência de Hypleurochilus fissicornis permitiu expandir sua distribuição geográ fica em cerca de 2.500 km ao norte. Esses resultados demostram que diversos aspectos relacionados a ictiofauna do ecossistema entremarés em substrato consolidado ainda permanecem pouco estudados no Brasil, e portanto, mais levantamentos da biodiversidade e dados ecoló gicos são necessá rios.

Trophic relationships in tidepool fish assemblages of the tropical Southwestern Atlantic

“…Its ecological importance is relevant considering the role it plays as feeding, breeding and nursery grounds for many organisms, especially for fishes and crustaceans (Gibson & Yoshiyama, 1999;Horn, Martin, & Chotkowski, 1999;Oliveira et al, 2016). Tropical ecosystems exhibit a wide range of inter-tidal habitats, including both unconsolidated substrates such as mudflats and sandy beaches (Andrades et al, 2014;Oliveira et al, 2016) and hard bottoms as such rocky shores and reef flats (Machado et al, 2015;Macieira & Joyeux, 2011;Macieira et al, 2015). One of the most striking features of the inter-tidal zone is when water is trapped in cavities and depressions on the substratum during low tide forming tidepools .…”

“…volume, surface area, depth and rugosity), substrate composition and physicochemical conditions (Macieira & Joyeux, 2011;Oliveira et al, 2016). However, factors influencing the organization and structure of tidepool communities remain understudied (Machado et al, 2015;Norton & Cook, 1999) and considerably less understood than those of communities exposed to the atmosphere at low tide (Zander et al, 1999).…”

“…However, despite the country's extensive coastline and high environmental heterogeneity, studies on tidepool fish communities are relatively scarce (e.g. Almeida, 1973;Almeida, 1983;Barreiros, Bertoncini, Machado, Hostim-Silva, & Santos, 2004;Cunha, Monteiro-Neto, & Nottinghan, 2007;Macieira & Joyeux, 2011;Machado et al, 2015;Macieira et al, 2015;Oliveira et al, 2016;Rosa et al, 1997), with a single unpublished work focusing on trophic ecology (Zamprogno, 1989). The identification of trophic guilds is fundamental to understanding the dynamics of fish assemblages, the functional role of species in the ecosystem and the factors responsible for organization and structure of communities (Castellanos-Galindo & Giraldo, 2008;Muñoz & Ojeda, 1997).…”

Checklist of the tidal pool fishes of Jeju Island, Korea

“…The island lies in the southernmost temperate region of Korea, and many subtropical and temperate species of fishes inhabit the coastal and adjacent waters of the island (Kim 2009). Many marine fish species use tidal pools for part of their life cycle (Andrade et al 2007, González-Murcia et al 2012, Choi and Lee 2013), so studies of the occurrence of fish species in tidal pools provide important information on local fish biodiversity and for the conservation of coastal ecosystems (Machado et al 2015, Torres-Hernández et al 2016). …”

Structure and composition of fish assemblages from São Sebastião Channel tide pools, southwestern Atlantic

“…At the southwestern Atlantic, studies on intertidal fishes are mostly faunal surveys (e.g. Almeida 1973, Rosa et al 1997, Machado et al 2015, but in the last decade this has changed, particularly in the Northeast (e.g. Cunha et al 2007, Cunha et al 2008, Godinho & Lotufo 2010 and Southeast Brazil (e.g.…”
